N.B. An illustration showing the parts breakdown for the Cup Drop Unit is
included in Section 12 - page 106.
7.6 Waste Level Probes
1. The waste level probes, fitted to the underside of the machine, detect the water
level in the waste tray.
2. The system consists of two springs set at different levels. When the water level
is high enough that both of the springs are immersed in the water a message is
displayed on the machine saying the waste tray is full and the machine is disabled.
N.B. The springs are set at two different levels in order to lessen the chance that
movement of water in the drip tray could accidentally disable the machine.
7.7 Brewer Unit - (Freshbrew Models)
1. The dual brewer unit provides both freshly brewed coffee and tea vends. The
coffee and tea ingredients are dispensed into the brewer unit via separate
canisters.
2. A 24v DC, 3.5 RPM motor, controlled by an index cam fitted to the drive shaft,
operates the brewer unit. The cam operates a switch which sends a logic signal
to the controller when the brewer is in the correct position.
Coffee Brewing
3. Water and coffee grounds are dispensed into the coffee brewing chamber. The
motor drives the piston up and mixes the coffee and water.
4. The motor drives the piston down and the resulting vacuum pulls filtered coffee
through the filter mesh.As the piston passes the coffee outlet adaptor, coffee flows
to the dispense head.The piston remains in this position for a while to allow the
coffee to drain away.
N.B. There are 4 programmable delay positions which can be set via the
freshbrew coffee selection timers.These delays could be set to zero to speed up
the vend cycle.
5. A separate mechanism, operated via the brewer drive pin, removes the coffee
grounds.The coffee wipe arm wipes the grounds from the filter mesh.They then
drop, via a deflector tray, into a waste bucket. The motor returns the piston to
its parked position.
